Bill Clinton is headed to Maine to help Democrat Mike Michaud, who is locked in a three-way race for governor.

The Michaud campaign boasted the Clinton rally on Sept. 2 in Portland reached capacity after only three hours after it was announced. There’s now a waiting list for tickets.

Michaud, a six-term congressman, is trying to unseat Republican Gov. Paul LePage, who has made headlines for telling President Obama to “go to hell” and calling the IRS “the new Gestapo.” Michaud and LePage are both polling in the high 30s, with independent Eliot Cutler trailing but still in double digits.

“I’ve always admired President Clinton for his ability to work across the aisle to get things done, which is something we’ve been missing here in Maine under Gov. LePage,” Michaud said. “Based on the reaction our invitation has received, it’s clear voters in Maine are extremely excited about this race and ready for a change.”

LePage is one of six Republican governors in danger of losing his job, according to the non-partisan Cook Political Report ratings. President Obama easily won Maine in 2012 and 2008, and Clinton carried the state in both of his presidential elections.
